摘要： Data payload is passed over a boundary from a sender module (SM) on one side of the boundary to a receiver module (RM) on the other side of the boundary. The SM has two or more multiplexers to pass the data payload over to a receiver storage register in the RM. Each multiplexer has 1) its own read address pointer lane coming from sequencing logic located on the RM side and 2) data slots to send data payload from that multiplexer across the boundary to the receiver storage register in the RM in a qualified event synchronization. The sequencing logic ensures that the multiple read address pointers going to the multiplexers have a fixed alternating relationship amongst themselves; and thus, the multiple read address pointers syncopate between each other to move the data payload across the boundary to provide 100% throughput.

摘要： An interconnect-power-manager (IPM) cooperates and communicates signals with an integrated-circuit-system-power-manager (SPM) in the integrated-circuit. The interconnect network (IN) is partitioned into multiple power domains and has hardware circuitry integrated into the IN to manage a quiescent state for all components in each power domain in the IN when a routing pathway for transactions in the IN spans across one or more power domain boundaries and causes interdependencies of power domains within the IN other than where the power domains of the initiator agent and final target agent of the transaction are located within. The SPM is configured to cooperate and communicate with the IPM to quiesce, to wake up, and any combination of the two, one or more of the multiple power domains within the IN.

摘要： A scannable logic unit includes one or more storage registers that maintain copies of data communicated from the scannable unit to registers in a nonscannable unit. When the scannable unit is subjected to a scan test, the registers will contain state information respecting that transfer to the nonscannable unit. When the scannable and nonscannable units are placed in a run condition, the registers supply to the nonscannable unit state information for continuing operation.

摘要： In an embodiment, an interconnect for an integrated circuit communicates transactions between one or more initiator Intellectual Property (IP) cores and multiple target IP cores coupled to the interconnect. Two or more memory channels make up a first aggregate target of the target IP cores. The two or more memory channels populate an address space assigned to the first aggregate target and appear as a single target to the initiator IP cores. The interconnect implements chopping logic to chop individual two-dimensional (2D) transactions that cross the memory channel address boundaries from a first memory channel to a second memory channel within the first aggregate target into two or more 2D transactions with a height value greater than one, as well as stride and width dimensions, which are chopped to fit within memory channel address boundaries of the first aggregate target.

摘要： A method, apparatus, and system are described, which generally relate to an integrated circuit having an interconnect. The flow control logic for the interconnect applies a flow control splitting protocol to permit transactions from each initiator thread and/or each initiator tag stream to be outstanding to multiple channels in a single aggregate target at once, and therefore to multiple individual targets within an aggregate target at once. The combined flow control logic and flow control protocol allows the interconnect to manage simultaneous requests to multiple channels in an aggregate target from the same thread or tag at the same time.

摘要： Various methods and apparatuses are described that provide instrumentation and analysis of an electronic design. A performance monitoring apparatus may be located on an interconnect of a fabricated integrated circuit. An event measurement module (EM) includes an event generator sub-module that generates monitoring events and event measurements associated with transactions between initiator intellectual property (IP) cores and target IP cores over the interconnect. The EM further includes a software visible register block that provides software access for controlling the EM on which one or more transactions to monitor and to configure one or more parameters associated with that transaction to track. The EM further includes a filtering sub-module that selects transactions to be monitored based on information received from the software. The performance counter module aggregates events and event measurements received from the EM into quantities of performance metrics associated with transactions between the IP cores over the interconnect.

摘要： An interconnect for an integrated circuit communicating transactions between initiator Intellectual Property (IP) cores and multiple target IP cores coupled to the interconnect is generally described. The interconnect routes the transactions between the target IP cores and initiator IP cores in the integrated circuit. A first aggregate target of the target IP cores includes two or more memory channels that are interleaved in an address space for the first aggregate target in the address map. Each memory channel is divided up in defined memory interleave segments and then interleaved with memory interleave segments from other memory channels. An address map is divided up into two or more regions. Each interleaved memory interleave segment is assigned to at least one of those regions and populates the address space for that region, and parameters associated with the regions and memory interleave segments are configurable.
